摘要： An integrated circuit is described herein. According to one or more embodiments, the integrated circuit includes a local oscillator with a voltage-controlled oscillator (VCO) that generates a local oscillator signal. Further, the integrated circuit includes a frequency divider coupled to the VCO downstream thereof. The frequency divider provides a frequency-divided local oscillator signal by reducing the frequency of the local oscillator signal by a constant factor. A first test pad of the integrated circuit is configured to receive a reference oscillator signal. Further, the integrated circuit includes a first mixer that receives the reference oscillator signal and the frequency-divided local oscillator signal to down-convert the frequency-divided local oscillator signal.

摘要： A light-emitting unit outputs an optical signal corresponding to an input electric signal. A light-receiving unit is electrically insulated from the light-emitting unit and outputs an electric signal according to the received optical signal as an output signal. In the light-receiving unit, a first light-receiving device outputs an optical current according to the optical signal. A second light-receiving device is provided not to receive the optical signal. A current duplication circuit duplicates a current flowing through the second light-receiving device. A current-voltage conversion circuit converts a current, which is generated by subtracting the current duplicated by the current duplication circuit from a current flowing through the first light-receiving device, into a voltage signal. A comparator output a result of a comparison between the voltage signal converted by the current-voltage conversion circuit and a threshold voltage as the output signal.

摘要： An integrated circuit package includes an encapsulation and a lead frame with a portion of the lead frame disposed within the encapsulation. The lead frame includes first and second conductive loops. A first voltage is induced between first and second ends of the first conductive loop in response to an external magnetic field that passes through the integrated circuit package. A second voltage is induced between third and fourth ends of the second conductive loop of the lead frame in response to the external magnetic field that passes through the integrated circuit package. The first conductive loop is coupled to the second conductive loop such that the first voltage between the first and second ends combined with the second voltage between the third and fourth ends substantially cancel.

摘要： Methods and devices are described for compensating an effect of aging due to, for example, hot carrier injection, or other device degradation mechanisms affecting a current flow, in an RF amplifier. In one case a replica circuit is used to sense the aging of the RF amplifier and adjust a biasing of the RF amplifier accordingly.

摘要： Communication between a wireless base-station and a microwave reflector link are enhanced by feeding back a portion of the transmitter signal, adjusted for phase and amplitude, to cancel ambient reflection blocker signals being received at the base-station. The microwave reflector link does not utilize a transmitter gain stage, but communicates data back to the base-station in response to modulating the reflections of its antenna (e.g., in gain and/or phase). The disclosure aids in the proper amplification and processing of reflection signals from the microwave reflector link, by canceling out the blocking signals which arise as background objects reflect transmitter signal energy back to the base-station.

摘要： In one or more embodiments, a plurality of PLC endpoints and a data processing circuit are configured to share information, in the form of data blocks over power lines in a power line communication (PLC) network. A first signal representing a transmitted one of the data blocks is received over a first one of the plurality of different communication channels. A second signal representing the transmitted one of the data blocks is received over a second one of the plurality of different communication channels. Information carried by said one of the data blocks is discerned, as a function of a signal versus noise measure associated with the first signal and the second signal, by combining energy from the first and second signals, and converting the combined energy for generating output data.
